Used MXR M133 Micro Amp Pre Effect Pedal

This used MXR M133 Micro Amp Pre Effect Pedal offers a dependable and transparent clean boost, making it a smart addition to any guitarist’s rig.

Its rugged all-metal construction and compact design reflect MXR's commitment to durability and quality, while true bypass switching protects your core tone when the pedal is disengaged. Made in the USA and fully functional in excellent condition, this Micro Amp represents a reliable performance tool that delivers nuanced or powerful boosts without altering your tone. Whether you're on stage or in the studio, it’s a trustworthy solution for players seeking clarity, presence, and control, powered by a 9V battery or an optional AC adapter (not included).
